JOHN F. WOITYNEK, OF LA SALLE, ILLINOIS.

DIRIGIBLE HEADLIGHT FOR CARS.

Specification of Letters Patent.

Patented May 9, 191].

Application filed January 16, 1911. Serial No. 602,906.

To all whom it may concern.

13: it known that l, JOHN F. VVorrvNnk, a. citizen of the United States,residing at; La Salle in the county of liasalle and State of Illinois,have invented certain newnnd useful lrnprovemei'lts in Dirigiblellcadlights for Cars; and I do declare the follow ing to be a full,clear, and exact description of the invcntitnl, such as will enablet.hers skilled in the art to which it appertains to make and use thesame. I

This invention relates to improreinents in dirigible head lights forcars and the like One object of the invention is to providea. head lightof this char-miter having means whereby the same is automatically turnedin the direction in which the ear is turned and means r-vhereby the lampis tilted when thus turned to throw the light directly onto the centerof the curved track.

With this and other objects in view the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be more fully described and particularly pointed out in theappended claims.

In the accompanying drawings: Figure 1 is a vertical longitudinalsectional view of the front end of a car showing my improved head lightapplied thereto; Fig. 2 is a bottom plan view of the same; Fig. 3 1s aside view of the lamp in turned position; Fig. 4 is a vertical sectionon the line t--4 of Fig. 1; Fig. 5 is a horizontal section on the line55 of Fig. 3; Fig. 6 is a detail perspective view of the lamp supportingbracket.

Referring more particularly to the drawings, 1 denotes the front end ofa car and 2 denotes the front truck. To the front end of the car issecured in any suitable manner, upper and lower forwardly projecting andhorizontally disposed bearing brackets 3 in which is revolubly mountedthe supporting and operating shaft 4 of my improved head light or lamp5. On the upper end of the shaft 4: is secured a horizontally disposedlamp supporting plate 6. Th lamp or head light 5 is pivotally connectedat its lower end adjacent to its front side to the front edge of theplate 6 as shown. On the bottom or lower end of the lamp at the rearside thereof is formed a segmental lamp tilting flange 7 in which,midway between its ends is formed a curved recess 8, the outer portionsof the flange between the recess and ends thereof thus formii'ig camsurfaces. In the upper bracket 3 below the flange 7 is :l'ori'ned a slot9 in which is rev olubly nioui'lted a double cone. shaped lamp tiltingroller ll) which is adapted to engage the flange 7 whereby when the lampis turned in either direction and the cam surfaces of the flange broughtinto engage ment with the roller the lamp will be tilted forwardly anddonmwardly thereby throwing the light directly onto the center of thetrack or directly in front of the war.

When the ear is running straight; ahead and the lamp is in its normalposition the rot-Ms 5 in the flange is engaged with the l'nlh'l' '11)thuspermitting the lamp to sit squarely on the supporting plate (1. Onthe lower end of the shaft -'lis fixedly mounted a sprocket wheel 11,said wheel being preferably secured to the shaft by a key and isprevented from l'ieeon'iing disengaged from the. shaft by a cap or nut12 screwed onto the lower end of the shaft. En gaged with the sprocketwheel 11 is a sprocket chain 13 the ends of which are connected byshort: coiled springs 14. to the operating rods 15, the inner ends ofwhich are provided with loops and connected to eye bolts '16 arranged inthe front cross bar of the truck 2 as shown. The operating rods 15 aresupported in operative position and prevented from sagging by means of atransversely disposed supporting bar 17 which is secured to the lowerside of the car platform as shown. By connecting the operating shaft 4with the front truck of the car as herein shown and described it will beobvious that when the truck is turned in one direction or the other asthe car passes around curves that the movement of the truck will beimparted to the shaft and the lamp to turn the same in the directionthat the car is traveling thus throwing the light continuously in frontof the ear or in the direction in which the same is traveling.

In order to prevent the lamp from being tilted forwardly too far by theenga ement of the cam surfaces of the flange with the roller 10 Iprovide a yielding connection for the upper end of the lamp saidconnection being here shown in the form of a coiled spring 18 one end ofwhich is connected to the rear upper portion of the lamp and the otherend to the front of the car.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Variouschanges in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as defined in theappended claims.

Having thus described my invention, what I claim is: p

1. In a dirigible head light for cars, a revolubly mounted lampsupporting shaft, means to operatively connect said shaft with the fronttruck of the car, to turn said shaft in unison with said truck, a lampsupporting plate arranged on the upper end of said shaft, a lamphingedly connected to said plate to tilt forwardly thereon when turnedin. the direction the car is traveling, at revolubly mounted lamptilting roller, and a segmental tilting flange secured to the lamp andhaving formed thereon cam roller engaging surfaces whereby when the Ilamp 1s turned to bring sald surfaces into engagement with the roller,said lamp will be tilted 'l'orwanlly and downwardly.

2. In a dirigilole head light for cars, a revolubly mounted lampsupporting shaft, means to operatively connect said shaft with the fronttruck of the ear, to turn said shaft in unison with said truck, a lampsupporting plate arranged on the upper end o'tj' said shaft, a lamphingcdly connectedto said plate to tilt forwardly thereon when turned inthe direction the car is traveling, at revolubly mounted lamp tiltingroller, a segmental tilting flange Secured to the lan'ip and havingformed thereon cam roller engaging surfaces wlun'eby when the lamp isturned to bring said surfaces into engagement with the roller, said lampwill be tilted forwardly and downwardly, and a yielding connection tolimit the tilting move ment' of the lamp.

in testimony whereof I have hereunto set my hand in presence of twosubscribing \v i l i'usses.
